72 Muhlenbergia, Volume 4 2 
The tall meadow rue, 7halictrum polygamum, which blooms 
in early summer, is often met in swampy ground, as well as 
Cardamine pennsylvanica, always confused in Gray’s Manual 
with the rare introduced Cardamine hirsuta. 
His name is attached to seven species of the great family 
Compositae, all of which, with perhaps the exception of Aster 
Phlogifolius, are found in the county. The other six are Eupa- 
tortum pubescens, plentiful on the island at the mouth of the 
Tucquan; Solidago hispida, common in fence rows and on edges 
of copses; .S. Zatwla, a dweller in swampy ground, common in 
the Dillerville swamp; .S. sguarrosa, found on rocky banks at 
Conewago; .S. «/mifolia, not very common, but occasionally met 
with along roadsides and on banks, and the common blue flow- 
ered swamp aster, Aster prenanthoides, plentiful in the Diller- 
ville swamp. . 
Not being familiar with the grasses and sedges, I can give 
very few of his species which occur in this vicinity, but of those 
known to me, we have of the grasses Andropogon furcatus and 
Panicum minus, aud of the sedges Eleocharis intermedia and 
Scleria paucifiora in the Dillerville swamp. Probably nearly 
all of the dozen species of Carex are found in the vicinity. 
His three species of willow, Salix cordata, S. discolor and 
S. Zuctda, all occur in the county. 
Although not a student apparently of the lower cryptogams, 
he collected a large number of mosses, and the vicinity of Lan- 
caster furnished many type specimens. In 1899 the distin- 
guished French bryologist, M. Jules Cardot, published in vol- 
ume 7 of the Bulletin of the Herbier Boissier, a paper on the 
“Revision des types d’Hedwig et de Schwaegrichen,” in which 
about 80 species are mentioned as having been collected by 
Muhlenberg in Pennsylvania, nearly all of them from near Lan- 
caster. In the list are two species dedicated to the collector, 
Bartramia Muhlenbergu and Funaria Muhlenbergi. Several 
other species amiong the cryptogams bear his name, as well as a
